Dall is my married name. I just recently branched into the Dall family research once I had completed my own family name. John and Agnes Lawson Dall of Kennoway are in the family tree of my husband David Dall. The line goes like this:
John and Agnes Lawson - Henry and Margaret Spittal - David and Agnes Watson Farmer - David and Bertha Sturton - David and Lorna Yates (me)
The Dall name is a lot more common than I originally thought.
